About

nc5ng was started in 2017 to bring North American Datum Conversion tools to a broader developer audience. With a focus on historic datums for use with Historical Topographic maps, the US Standard Datum (USSD) in particular.

Initially the project focus was documentation, porting the build pipeline, and low-level wrappers for the most direct manipulation and data analysis.

By 2018, the build pipeline for NADCON5.0 was successfully ported to GNU Make and work on python wrappers and processing libraries was begun. The initial work is focused on completeing the data wrapper API, then recreating the build pipeline and output visualizations in python for on-the-fly transformations.

Project Goals:

Adapt the existing programs to make it suitable for use as a stand-alone tool in Continuous Integration / Continuous Deployment Data Processing Pipelines.

Construct proj.4 and WKT compatible datum definitions for inclusion of USSD and other datums into common GIS tools and spatial reference databases,
